Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 32,621,575, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 32,621,575 | |
| -1 | -32,621,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,621,575.
Example:
1 x 32,621,575 = 32,621,575
and
-1 x -32,621,575 = 32,621,575
Notice both answers equal 32,621,575
With that explanation out of the way, let's continue. Next, we take the number 32,621,575 and divide it by 2:
32,621,575 ÷ 2 = 16,310,787.5
If the quotient is a whole number, then 2 and 16,310,787.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,621,575 | |
| -1 | -32,621,575 |
Now, we try dividing 32,621,575 by 3:
32,621,575 ÷ 3 = 10,873,858.3333
If the quotient is a whole number, then 3 and 10,873,858.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,621,575 | |
| -1 | -32,621,575 |
Let's try dividing by 4:
32,621,575 ÷ 4 = 8,155,393.75
If the quotient is a whole number, then 4 and 8,155,393.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,621,575 | |
| -1 | 32,621,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 475 | 665 | 3,325 | 9,811 | 49,055 | 68,677 | 186,409 | 245,275 | 343,385 | 932,045 | 1,304,863 | 1,716,925 | 4,660,225 | 6,524,315 | 32,621,575 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -475 | -665 | -3,325 | -9,811 | -49,055 | -68,677 | -186,409 | -245,275 | -343,385 | -932,045 | -1,304,863 | -1,716,925 | -4,660,225 | -6,524,315 | -32,621,575 |
